Grating-based x-ray dark-field mammography: Assessing complementary imaging information in simple cystic lesions and typical fibroadenoma.

ABSTRACT:

Background

A significant proportion of false positive recalls of mammography-screened women is due to benign breast cysts and simple fibroadenomas. These lesions appear mammographically as smooth-shaped dense masses and require the recalling of women for a breast ultrasound to obtain complementary imaging information. They can be identified safely by ultrasound with no need for further assessment or treatment.

Purpose

Grating-based x-ray dark-field breast imaging allows contrast formation based on both attenuation and small-angle x-ray scattering and provides complementary imaging information in one single acquisition.

Methods

Experiments with ex-vivo mastectomy samples were performed with a three-grating Talbot-Lau interferometer using a laboratory-based polychromati
